The Urban Dictionary T-Shirt

A nonsensical or illogical legal defense (especially one postulated by an unpopular defendant such as Microsoft or RIAA). The phrase comes from the animated TV series South Park, where an attorney exhorts a jury to acquit his client based solely on his contradictory arguments.

"Although my client's fingerprints were all over the murder weapon and he was seen by 50 eyewitnesses at the scene of the crime, the Sun rises in the East so you must find him innocent."
